I found that my problem was unclear instruction about the timing between jumping and popping. One day when I was watching a slowmo ollie video though, I noticed that the skateboarder already was beginning to jump (at least his body was already going in an upward motion) before snapping the board off the ground. That was a critical change I needed to make in order to get it working. I had been trying to pop the board while all my weight was still pushing down on it (kind of an obvious mistake, but I somehow overlooked this). Hope this helps somebody.
Choosing a skateboard deck can be approached in a few different ways: you can choose your board based off the graphic, the brand, the shape, the width, or even the color. For most skateboarders, it’s a combination of all these factors, but if you’ve never skateboarded before, you may not know what shape, width, or brand you like best. In this case, choosing your favorite graphic would make total sense.
The wheels of a skateboard are usually made of polyurethane, and come in many different sizes and shapes to suit different types of skating. Larger diameters (55–85 mm) roll faster, and move more easily over cracks in pavement and are better for transition skateboarding. Smaller diameters (48–54 mm) keep the board closer to the ground, require less force to accelerate and produce a lower center of gravity which allows for a better response time, but also make for a slower top speed and are better for street skateboarding. Wheels also are available in a variety of hardnesses usually measured on the Shore durometer "A" scale. Again like car tires, wheels range from the very soft (about Shore A 75) to the very hard (about Shore A 101). As the A scale stops at 100, any wheels labeled 101A or higher are harder, but do not use the appropriate durometer scale. Some wheel manufacturers now use the "B" or "D" scales, which have a larger and more accurate range of hardness. Modern street skaters prefer medium-sized wheels (usually 51–54 mm), as small wheels with lighter trucks can make tricks like kickflips and other flip tricks easier by keeping the center of gravity of the skateboard closer to the deck, thus making the deck easier to spin. Street wheels are harder (A 100/A 101). Vertical ramp or "vert" skating requires larger wheels (usually 55–65 mm), as it involves higher speeds. Vert wheels are also usually slightly softer (A 98/ A 99), allowing them to maintain high speed on ramps without sliding. Slalom skating requires even larger wheels (60–75 mm) to sustain the highest speeds possible. They also need to be soft and have better grip to make the tight and frequent turns in slalom racing. Even larger wheels are used in longboarding and downhill skateboarding. Sizes range from 65 mm to 100 mm. These extreme sizes of wheels almost always have cores of hard plastic that can be made thinner and lighter than a solid polyurethane wheel. They are often used by skateboard videographers as well, as the large soft wheels allow for smooth and easy movement over any terrain.

To get higher ollies, I would suggesting resting your back foot on the very end of the tail and the front foot in the middle of the deck to allow for more slide. Popping as hard as you can and catching your board in the groove of the nose with you ankle practically resting in the groove will level the board out in the air. after this initial movement slide you feet back to the bolts on the tail and nose to ensure a clean landing.

In fact, we can work out how you need to steer the skateboard. Tracker has a nice feature that we'll call 'force arrows'. These arrows show you how much force acts on an object at every instant, and in which direction the force acts. So for example, if you were to kick a ball into the air, while the ball was mid-flight, this arrow would always point down and be the same length, even though the ball is moving forward. That's because the only force acting on the ball is gravity, which pulls it straight down, and acts with a constant strength. (For those of you who've studied physics, these arrows denote the acceleration of the center of mass, which by Newton's second law is proportional to the net force acting on the skateboard.)
It’s not just standard deck sizes that are available for creating or replacing your board. You can just as easily get a great longboard deck to work on in your basement or garage. One of the best and best reviewed options out there is the Loaded Boards Poke Longboard Skateboard Deck. This standard-design longboard deck has it all to help you make the ideal board. 
We’re assuming if you’re trying to learn how to do an ollie, you’re probably pretty new to skateboarding. You may already know whether you’re goofy or regular footed, but if not, try taking a quick hop onto your board with the intention of rolling forward (you might want to try on carpet first so you don’t slip backwards). If you’re left foot naturally ends up towards the front of your board, you’re regular-footed. If you ended up putting your right foot first, you’re goofy-footed.
If you are completely new to skateboarding, consider taking a minute to read through the Skateboard Decks Section in our Buyer’s Guide will be helpful, but a good rule of thumb is: the bigger your feet, the wider your board should be. If you wear a size 9 and up, you can’t go wrong with buying an 8” board. Narrow boards are easier to flip while wider boards are more stable, but there are no hard and fast rules to skateboarding. The only way to really find out what you like is by trying new shapes, sizes, and brands. Brands like Welcome, Baker, Chocolate, Deathwish, and Element all have a wide variety of sizes, shapes, and graphics.
